Question

The plasmid pBR322 contains two antibiotic resistance genes:

• A. ampR and tetR
• B. kanR and catR
• C. neoR and hygR
• D. bla and specR

Hint:

When working with plasmid vectors, remember the specific resistance genes included for selection, such as ampR and tetR in pBR322.

Answer 1

The Correct Option is A

The plasmid pBR322 is a commonly used plasmid vector in molecular biology. It contains two antibiotic resistance genes: ampR (for ampicillin resistance) and tetR (for tetracycline resistance), which are used for selection of transformed bacteria.
